footnotes =François Hennebique (
April 26 ,1842 –7 March ,1921 ) was a Frenchengineer and self-educated builder who patented his pioneering reinforced-concrete construction system in [1892] , integrating separate elements of construction, such as thecolumn and the beam, into a singlemonolithic element. The Hennebique system was one of the first appearances of the modern reinforced-concrete method of construction.Hennebique had first worked as a stonemason, later becoming a builder, with a particular interest in restoration of old churches. Hennebique's Béton Armé system started out by using concrete as a fireproof protection forwrought iron beams, on a house project in Belgium in 1879. He realised however, that the floor system would be more economic if the iron were used only where the slab was in tension, relying on theconcrete in the compression areas. [McBeth, Douglas: "Francois Hennebique (1842-1921) - Reinforced concrete pioneer", Proceedings of the Institution of Civil Engineers, 1998] His solution was reinforced concrete - a concrete slab with steel bars in its bottom face.His business developed rapidly, expanding from five employees in Brussels in 1896, to twenty-five two years later when he moved to Paris. In addition, he had a rapidly expanding network of firms acting as agents for his system. These included L.G. Mouchel in Britain, and Eduard Zublin in Germany. [McBeth, op.cit.]
The first building erected using this system was the 1897 [http://www.welshwales.co.uk/weaver.htm Weaver Building] in what was then the Docks area of
Swansea , but it was demolished in the 1980s when the docks were redeveloped to make way for theMaritime Quarter development. A fragment of the original building is preserved by the side of the riverTawe , where a plaque commemorates Hennebique and his achievement. Between 1892 and 1902, over 7,000 structures were built using the Hennebique system, including buildings, water towers and bridges. Most of these were by other firms licensing the technology, although Hennebique designed some structures himself, including the 1899 bridge at Châtellerault (pictured).
